Stealth - the new Rina Walker thriller! (Rina Walker 4) - Hugh Fraser

Gratuitous violence galore ... but we also have a vividly seedy mid-to-late 60s Soho setting (which I know the author wrote from his own experiences), organised crime, espionage, and despite all the weird s*** in this series, Rina is a fun take on the hired gun character.
